Buying Guide

  • Animal target and needs: Choose a product aligned with whether you’re addressing weight gain in horses or dogs/cats, and consider age-specific requirements such as joint support, digestion, and coat health.
  • Calorie density and fat content: Higher fat and calorie levels typically drive faster weight gain but may require gradual introduction to avoid digestive upset.
  • Digestibility: Probiotics, digestible fats, and balanced starches help maintain gut health, particularly in seniors with sensitive digestion.
  • Nutrient balance: Look for blends that include essential amino acids, calcium/phosphorus balance, omega-3 fatty acids, and vitamins/minerals to support overall vitality and immunity.
  • Palatability: For animals with reduced appetite, palatable formulations (crumble textures or tasty flavors) improve adherence to a gain plan.
  • Veterinary guidance: Weight gain plans should be monitored to avoid excess fat, ulcers, or metabolic issues, especially in older animals with existing conditions.
  • Fade in/out strategy: Start with a gradual transition by mixing a portion of the supplement with regular feed, then adjust as needed based on appetite and weight response.
  • Quality and sourcing: Prefer products with transparent ingredients and clearly stated fat sources, probiotics, and essential fatty acids.
